java - Android Studio文字编辑器会删除文字，而不是允许常规编辑(Android studio text editor erases text instead of allowing normal edit)

Question

I have worked with several IDE and code editors but this android studio am using is a real mess, when I place a cursor in the code i want to edit or add code to it, instead of allowing normal edit it just deletes what ever code is there and replaces it with what I type.

(我已经使用过多个IDE和代码编辑器，但是使用的这个android studio真是一团糟，当我在代码中放置光标时，我想对其进行编辑或添加代码，而不是允许其进行常规编辑，只是删除了曾经存在的代码并用我输入的内容替换它。)

For example if i the space key between the public and void it will erase the void instead of creating the space am requesting it to provide.

(例如，如果我在public和void之间使用空格键，它将删除该void，而不是创建要求其提供的空间。)

Answer 1

Maybe you have the 'ins' pressed on your keypad.

(也许您在键盘上按下了“ ins”。)

Press numlock, and then 0 to turn off the insert function.

(按numlock，然后按0关闭插入功能。)

If it doesnt work, try pressing the numlock again and then press 0.

(如果不起作用，请尝试再次按数字锁定，然后按0。)
